Mesothelioma of spermatic cord: electron microscopic and histochemical characteristics of its mucopolysaccharides.

A mesothelioma of the spermatic cord occurred at the site of multiple hernial repairs. The aggressive biologic behavior of this tumor is exhibited by its early lymph node invasion and extensive metastases to the pleural cavities, lungs, and spleen. These tumor cells contained a large amount of stable of stable glycogen-like carbohydrate insoluble in formalin and tolerating postmortem changes. Electron microscopy revealed features similar to those mesotheliomas arising from body cavities.
